ADDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,823, dated January3, 1882.

Application filed March 3], 1881. (Model.)

tion of the construction and operation of the same, reference being badto the. accompanying IO drawings, forming part of this specification.

This my invention relates to a certain new and useful improvement inadding-machines, consisting, first, in a small frame of suitable sizewith a cog-roller working on bearings near the top of the frame,extending about three-fourths of the entire length of the frame, theremainder being made up by a stationary stud-pin secured in the frame,the end of which is made to answer as a journal-bearing for thefirst-named roller,which,when operated. is held in position at eachmovement by a pawl secured to the frame at the end. This last-namedcog-roller is provided with a small indicatorpulley on the end next tothe stud-pin, with a flange on the leftside, and a face wide enough toreceive a series of figures from 1 to 10. In connection with thislast-named pulley, two others of similar dimensions, with flanges on theside and figures on the face, are made to 0 work loosely on the stud-pinat the end of the roller, which roller and pulleys are operated by aseries of cog-segments (nine in number) hinged to the ends of smalllevers which work loosely on a stationary rod near the base of the 3 5frame, each of which is provided with a spiral spring around the rodconnecting with the levers, for the purpose of replacing them afterbeing pressed down in its operation, which is done somewhat similar tothat of an ordinary o piano, the end of the levers being provided withconnections, to which a set of vertical pins are hinged, the upper endsof which are each provided with a small button shaped knob, with figuresrunning up from 1 to 9, in addition to the cipher, and by pressing downany one of these knobs, which represent the figures in the column of thebook, said figure will be turned up and shown on the first pulley, whichrepresents units up to 10, and when above that number the next pulley,

which represents tens, will be turned to indicate the number of tens,and when above tens the third pulley, which represents hundreds, will beturned by the second to indicate the number of hundreds, and so on inlike manner to any number of thousands. The cog-segments which operatethe roller and first pulley are each provided with the required numberof cogs to turn up the figure on the pulley indicated by the knobpressed down. The second and third pulleys are operated by the first bymeans of a trigger on the inside face, which catches a three-pointeddevice secured to the pinion which operates the second pulley, andthereby turns it one figure at a time with each revolution of the firstpulley until a full revolution of the second is made, when the triggeronitcatchesasimilar three-pointed device and turns the third pulleyonefigure at a time with each revolution of the second,therebyindicating hundreds,and wh en thus operated each pulley is held inposition by means of another somewhat similar three-pointed device,which works against the flange of the pulleys for that purpose. Theselast-named pinions and three-pointed devices, by which the second andthird pulleys are operated, are secured firmly together and made to workloosely on a small rod passing through the upper ends of vertical armsextending up from the prongs of a bifurcated lever hinged to thelever-rod below by means of arms extending down from the prongs, and isfurther provided with a spiral spring in front to replace it after beingpressed down to ungear the pinions and set the pulleys, which alwaysremain in gear; but' when necessary to set them preparatory tocommencing operations the right-hand part of this last-named leverextends down under the first pnlley,with a catch on the end tohold itwhen set. The frontof the parts has asmall shaft working loosely inbearings, with two pins extending in under the three-pointed devicesthat hold the pulleys, and are pressed up by a spiral spring on theshaft. This shaft is further provided with an arm extending down andresting on a small block on the frame, to

' answer as a stand for holding up the lever in the end su'llicientlylong to extend through a vertical slot in the operating-leverO, andconnects with the bar of the rack, which operates the wheels in settingthe pulleys preparatory to commencing operation, which is done by simplydrawing back the rack and pressing it down until it engages with thepinion, and by pressing it in the pulleys will be turned.

The object of this my invent-i011 is to provide a machine for addingfigures that will be cheap, durable, reliable, and not likely to get outof order, and by means of which much valuable time and labor are saved,thereby greatly assisting book-keepers and others in .adding up theiraccounts, all of which I attain by the mechanism illustrated in thedrawings, in which- Figure 1. is a perspective view of the machine,showing its general construction. Fig. 2 is a perspective view of themachine, taken from the back, with the cover removed to show theinterior arrangement of the several parts. Fig.3 is a top view of thedouble operating-lever, showing the indicator-pulleys and othermachinery connected therewith. Fig. 4 is a side elevation of the doublelever, showing the stand and other devices connected with it. Fig. 5 isa side elevation of one of the single operatingrlcvers, showing thecog-segments and additional lever to which it is hinged, and also theplates which separate them. Fig. 6 is a top view of theoperating-levers, showing the levers, cog-segments, and plates betweenthem.

Similarletters refer to similar parts through-- out the several views.

This my invention will be more fully illustrated in detail in thedrawings, in which- A A represent the frame, which is made of metal andin form as shown in the drawings.

B is araised base on theframe, to which the segments or operatingleversare hinged.

U is astandon the baseB, through which arod, D, passes, and to which theoperating-levers E E are hinged near their centers, and further providedwith spiral springs F F around the rod D, connecting with the levers,for the purpose of replacing them after being pressed down in theiroperation. The ends of these levers E E, where they connect with thecog-segment lever, are each provided with a slit, as shown in Fig. 5,which works on a stationary-pin in the lower point of the cog-segmentsG, and also passes through a vertical slot in lever H, which is alsohinged to the rod D at the side of lever E, and thereby gives motion tothe segment G by the operation of the levers E. This last-named lever Hhas two teeth in the extreme end, to

answer as a catch or stop for the roller 0 when turned by the segment Gby pressing down lever E.

II are thin pieces of metal secured to the base B between the levers E,and are held in place at the top by the rod J, which passes throughthem.

K is a flange on the metal pieces I, and L are small pins on the side ofthe segments G, which passes up over the flanges l\ in rising, but dropsunder them in falling.

M M are the button-shaped knobs and stems by which the levers E areoperated.

N N are blocks upon which the segments Gr rest when replaced.

0 O is a double lever secured together in the center by abit'urcatedbrace, P, sufficiently wide apart to receive the pinions andthreepointed devices thatoperatcthepulleys. These lovers 0 0 have each avertical arm, Q, above and R below. By means of the latter they arehinged to the rod D on the base.

S is a pin through the ends of the arms Q, and T are sleeves on the samepin. U U are pinions on these sleeves, for operating theindicator-pnlleys.

V V are three pointed devices, for givinginotion to the pinions U whencaught by the triggers X X on the first and second pulleys, and therebytransmitting motion to the third. 7 is another somewhat similarthree-pointed device, which works on the flange of the pulleys to keepthem from turning when set, but will turn in a recess in the flange atthe trigger when the pinion is turned. These two threepointed devicesand the pinions that turn the pulleys are all secured firmly on the samesleeve, side by side.

Y Y are pins in the shaft Z, for pressing up against the three-pointeddevices 7 to prevent the pinions U from turning when thrown out of gearin setting the machine, and are held in position by the spring A.

B is a stand for holding up the lever O to keep the pinions Uin gearwhile in operation; but when necessary to set the pulleys ready for usethe lower end of this stand is tripped off the block (1, so as to reston the projection D until the pulleys are set, when it is raised andreplaced on the block with the pinions in gear, ready for use. Thisstand B is operated by means of the arm E, which has a pin in the endpassing through a vertical slot in the end of lever O, and connects withthe bar F, upon which the cog-rack G" is made to slide. This rack G isintended for the purpose of setting the machine preparatory tocommencing, the bar upon which it slides being hinged to the lever O atone end and to the stand 11 at the other, so that when pressed down bythe bandle I it gears into the pinion J of wheel K, which works into theroller-pinion L, and thereby turn s the pulleys to their proper places,after which the rack is raised or replaced by a spring, and the pulleyis left free to operate upon. M is the stand on which they work.

N is an arm of lever 0, extending down under the first pulleys, with acatch on the end for holding it in place when set.

Oisafluted cog-rollerextendingaboutthreefourths of the length of theframe, one end of which works in a bearing in the frame, while the otherworks on a stationary stud-pin extendingout from the frame.

P is a pulley secured firmly on the end of the roller, and by means ofwhich the others are operated, which is done by the triggers X X on theside aftera full revolution has been made, when they will be turned bythe pins Q and it acting against the catches V in the face. Thesepulleys P, S, and T are all made in form as shown in the drawings, withletters on the face from 1 to 10, or to a cipher.

U is a pawl on the frame, to hold the cogroller 0 when set.

The pinions U and three-pointed devices V- and W, that operate theindicator-pulleys, may be made as above described, or, if necessary, maybe dispensed with entirely; and two separate pinions of double length,with a part of each alternate cog cut away, may be substituted in theirplaces by hinging them on a pin sliding in hearings in front of thepulleys, with a spiral spring on the left end of the pm ions to keepthem in gear, but, when necessary to nngear them to set the machine, thepin is forced to the left bymeans of a lever working in bearings below,having an arm extending across under the rack G, and also a vertical armextending up so as to press against the end of the pin when the arm ispressed down by the rack G, when necessary to un gear them to set themachine.

Having thus fully described the nature and object ofthis my invention,what I claim as new, and desire to secure by Letters Patent, in amachine for adding figures, is

1. In a machine for adding figures, having a metal frame, the flutedcog-roller O and indicator-pulleys P S, and T, in combination with theroller-pinion L, wheel K, pinion J, and rack G, for setting the machine,substantially as herein described, and for the purpose set forth.

2. In a machine for adding figures, having a cog-roller, O, and pulleysP, S, and T, the' double lever O, with its extended point N, incombination with the stand B, shaft Z, rods Y, and spring A, also thepinions U and threepointed devices V and W, when arranged,constructed,and operated substantially as and for the purpose setforthl 3. In anadding-machine having a cog-roller, 0, pulleys P, S, and T, thecombination of the levers E, springs F, lever B, cog-segments G, andplates Iwith the flanges K, substantially as herein described, and forthe purpose set forth.
